Are you looking to save money on your next cabling project by learning how to terminate coaxial cable yourself? As a seasoned expert in the cable industry, I’m here to guide you through the process step-by-step. In this comprehensive article, we’ll cover everything you need to know to confidently terminate coax cable with the precision and reliability of a professional.

Coaxial cable is a versatile workhorse used to transmit a wide range of signals, from cable TV and internet to high-quality audio. By mastering the art of coax termination, you’ll be able to tackle any project that comes your way, saving on labor costs and gaining a deeper understanding of these critical cable systems.

Gathering Your Tools

Before diving in, let’s ensure you have all the necessary tools and materials on hand:

• Coaxial cable (RG-6 is most common for residential applications)
• Coax compression connectors (F-type for CATV/satellite or BNC for video/RF)
• Coax cable stripper tool
• Compression crimping tool
• Cable cutters
• Connector installation tool

When it comes to tools, investing in quality pays off. I recommend using precision compression connectors and a reliable stripper/crimper combo tool. Cheaper twist-on or crimp-style connectors may be tempting, but they often result in subpar connections prone to signal loss and interference.

Preparing the Cable

Step 1: Measure and Cut

Start by measuring out the length of cable needed for your run, adding a few extra inches to account for any trimming. Use your cable cutters to cleanly slice through the coax at a 90-degree angle. A straight cut is crucial for proper connector alignment.

Step 2: Strip the Outer Jacket

Next, use your coax stripper to remove about 1/2 inch of the outer jacket. The key here is to apply firm, steady pressure while rotating the tool around the cable. You’ll feel it slice through the tough exterior without damaging the delicate shielding underneath.

Step 3: Expose the Center Conductor

With the outer jacket removed, you’ll see the braided copper shielding and metallic foil. Carefully peel these layers back to expose the inner dielectric insulation and copper center conductor.

Use your fingers or needle-nose pliers to gently pull the shielding away from the center, ensuring it remains intact. Then, trim the dielectric to leave about 1/4 inch of bare center conductor protruding.

Attaching the Connector

Step 1: Slide on the Connector

Now it’s time to slip your coax connector onto the prepared cable end. Align it so the center conductor slides into the connector’s pin, while the outer shielding makes contact with the connector body. You may need to give it a firm push to fully seat the connector against the outer jacket.

Step 2: Crimp It Like You Mean It

With the connector in place, it’s time to break out the compression crimping tool. This specialized tool uses immense pressure to permanently lock the connector onto the cable for a solid, reliable connection.

Insert the connector into the appropriate die on the tool, ensuring proper alignment. Then, squeeze the handles firmly until you feel and hear the crimp snap into place. Don’t be afraid to put some muscle into it – a tight crimp is essential!

Testing Your Work

Before calling it a day, take a moment to visually inspect your newly terminated coax cable. The center conductor should be flush with or slightly protruding from the end of the connector, and the connector should feel secure with no wiggling or looseness.

As an extra precaution, I always recommend testing the cable with a coax tester or multimeter to verify signal integrity and catch any shorts or opens caused by improper termination. Trust me, there’s nothing more frustrating than fully installing a faulty cable run!

Pro Tips for Perfect Terminations

In my decades in the cable industry, I’ve learned a few tricks of the trade when it comes to coax termination:

• Consistency is key. Especially if you’re working with multiple cable brands, ensure your tools are properly adjusted for each type. Using the wrong stripper settings is a recipe for damaged shielding and shoddy connections.
• Don’t neglect the shielding. That thin foil layer beneath the braid is critical for signal isolation and noise rejection. Trim it to the same length as the braid to maximize shielding effectiveness.
• Give yourself some slack. When running coax, always leave a bit of extra length at each end to accommodate termination and future maintenance. Trying to stretch a cable to fit is asking for kinks, stress, and premature failure.
• Invest in quality connectors. Not all coax connectors are created equal. Look for options with robust construction, corrosion-resistant plating, and easy-to-use compression designs. Saving a few cents per connector is rarely worth the headache of dealing with poor connections down the line.

Conclusion

Learning to terminate coax cable is a valuable skill for any DIYer or cable professional looking to save time and money. By following these step-by-step instructions and investing in quality tools, you’ll be able to achieve reliable, high-performance connections that rival those of seasoned pros.

While it may seem daunting at first, I promise that with a little practice, you’ll be cranking out perfect coax terminations in no time. So go ahead and give it a shot – your wallet and your future projects will thank you!
